How do you determine if its your actual period or spotting?

Ok so the first day of my last period was Sept. 27 2012 and the day I was supposed to get my period Oct. 25th all I had was light pink streaks when I wiped it only lasted that day and I still haven't had my period. I've also been extremely tired lately like I can't stay awake for anything. I mean I wake up a couple of times because I just can't get comfortable. I also have been having lower back pains and little pains on the lower and middle parts of my abdomen but nothing really painful and most of the time during the day I don't know whether I want to throw up or poop. But even when I try neither come. I just can't get rid of this nausea feeling but I never throw up. I had some of these feeling before but I wasn't pregnant but this time there are more symptoms. And when I actually get to have a bowel movement which have become rare lately its always diarrhea. Lately I've been having these crying spells for absolutely no reason like I dropped a piece of paper and I cried. And my fiance put his work shirt on the bed and I completely flipped out and then just started crying even though that's where he normally puts it. ot sure if these are pregnancy symptoms. Please help

thanks for all the advice i was just wondreing i spotted all last weeek then i strated to get two days of heavier bleeding i dont know if it is my period just because i just started taking the bc pills last month. some help i need to know since i had a condom brak on me and i missed a pill

Am confused too because in june i went to periods at the end of the month wich is on the 27th or so,and the period was normal..On the 5th of July i slept with my boyfriend and then i used morning after pills and the pharmacist told that am gonna go to periods again and then on the 9th i slept with my boyfriend and then he did pull out and i didnt use morning after pills this time because i was still waiting for the periods..On the 14th of July i went to periods and the bleeding was normal..So now i have started my periods yesterday for August but am stressed can i be pregnant..From the story i have just shared is there a possibility that i might be pregnant...I have used two home pre tests and they are negative but am still worried..

I am 17, and I am sexually active. My boyfriend and I had unprotected sex last month, a few days after I was off my period. He pulled out but there is still the risk..... this morning I was happy to find out I got my period, but then when I went in the bathroom I noticed it was very little blood. I've been reading a lot about implanation, but I'm just scaring myself, my period wasn't late, welll what I though might be my period, can you tell me what's going on?

Not sure what to think I should of started my period on july 30th but didn't start spotting until august 5th. Now 5 days later spotting has increased slightly but still only when i wipe no need for tampon or pad. My usual period lasts from 5-7 days the first 4 very heavy flow usually use both super tampon and overnight pads together sorry for so much info. I am 33 years old have been feeling bad for a couple of weeks now. I just want to feel better already . Would this be my period? Please help, I emailed my doctor but have not received a reply

^this is the same person as above. I forgot to mention that I have also been having slight on and off back aches in addition to the dull lower abdomen aches. They sometimes are in the middle of my back and sometimes in the lower part of my back. I very rarely have back aches.

Last week Wednesday (the 25th) I went out to a party. Unfortunately, I had a little too much to drink and was admitted to the hospital. It was not alcohol poisoning, rather just too much alcohol in my system. Upon calling a few days later, i was told that i was administered a pill in the hospital for treatment. (i do not know the type of pill). Anyways, I started feeling dull lower abdomen aches around Friday. I had them up until today when the aches turned into period cramps and I got my period. However my period normally starts out heavy and ends light but this time it's not as heavy. I never usually cramp before my period, especially so early. Is this normal? Thanks so much for your help.

I need some thoughts. So about 4 or 5 days ago me and my boyfriend had a condom break during sex, i am on birth control and havent missed any pills in a few months. But yesterday i thought i was starting my period but its about a week a early and i usually get it the same time every month due to my birthcontrol. And its isnt normal either, its a dark red almost brownish color and os light which my period usually is also it isnt consistent it will stop for an hour or so and come back. Should i take a pregnancy test after the two week mark goes by?
